  • Behind the Scenes: LINUX Unplugged | Jupiter Extras 64

    We share what goes into making LINUX Unplugged special, and have a laugh at some of our bad ideas from show past.

  • OpenType, Harfbuzz, Qt : Not exactly a love story

    As far as ideas go there are a couple of approaches one is to follow the way Scribus does, which offloads the rendering to something like cairo which could handle this in a much better way. That would also require us to develop a couple of intermediate data structures that could hold the info, but that is not the biggest challenge. The problem here is the text editor dialog cause then you got relay what is being displayed on the canvas to the text editor dialog. And there you have to draw the cursor. Unfortunately drawing the cursor will be the biggest challenge here.

    The other way is to write a new Text Engine and hook it up into Qt's API, which is to follow the following interface of QTextLayout if I going the right way. That way we won't have to worry about the text editor widget stuff. But I haven't explored this route that much and probably unaware of the challenges.

    As a basis for both, I do have a basic proof of concept ready, which could be taken for a ride from here. It uses libraqm which a thin wrapper over HarfBuzz, FriBidi and FreeType.

  • Cybersecurity Firm Hired By Voatz To Audit Its System Finds Voatz Is Full Of Vulnerabilities

    Mobile voting app Voatz is still a mess. Two years ago, West Virginia decided to give the app a spin to allow some voters to vote from home during the midterm elections. Nobody in the security world thought this was a good idea. The only people who did feel this was a safe, secure way to collect votes were state legislators and Voatz itself. Some early poking and prodding by security researchers immediately found problems with Voatz's handling of votes, including out-of-date SSH and unproven facial recognition tech that was supposed to verify voters by matching their selfies to their government IDs.

  • TSA Admits Liquid Ban Is Security Theater

                             

                               

    Interesting context:

                               

    The TSA can declare this rule change because the limit was always arbitrary, just one of the countless rituals of security theater to which air passengers are subjected every day. Flights are no more dangerous today, with the hand sanitizer, than yesterday, and if the TSA allowed you to bring 12 ounces of shampoo on a flight tomorrow, flights would be no more dangerous then. The limit was bullshit. The ease with which the TSA can toss it aside makes that clear.

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
